DETAILED DESCRIPTION

The inner frame of a tobacco industry pack may increase the rigidity of the pack such that the tobacco industry products held therein are better protected from mechanical damage. The lid and inner frame also engage by friction upon opening and closing the lid and so reduces the risk of the pack accidentally opening.

A pack 1 is shown in FIG. 1 and comprises a generally parallelepiped container having a body 2 and a hinged lid 3. The pack 1 has major front and rear walls 4, 5, minor side walls 6, 7, a bottom wall 8 and a top wall 9. The front, rear and side walls 4, 5, 6, 7 comprise front, rear and side wall body panels 4 a, 5 a, 6 a, 7 a, and front, rear and side wall lid panels 4 b, 5 b, 6 b, 7 b. The hinged lid 3 is integrally connected to the body 2 at a folding hinge line 10 between the rear body panel 5 a and the rear lid panel 5 b and is pivotable between an open position in which an access opening 11 in the top of the body 2 is exposed to allow access to tobacco industry products contained therein, and a closed position. An inner frame 12 having a front panel 23 and side panels 24, 25 is disposed within the body 2 of the pack 1 to project out of the opening 11 therein. The inner frame 12 may include a cut-out 22 in the front panel 23 to provide easy access to the contents of the pack 1.

FIG. 2 shows a blank 21 used to form the inner frame 12 of FIG. 1. The blank 21 comprises a single sheet of material, such as cardboard, that comprises a front panel 23 that meets side panels 24, 25 at a first fold line 16, 17. The blank 21 is folded at each fold line 16, 17 and is inserted into the body 2 so that the side panels 24, 25 extend at right angles to the front panel 23. When the inner frame 12 is inserted into the body 2 the side wall body panels 6 a, 7 a abut the inner frame side panels 24, 25 and the front wall body panel 4 a abuts the inner frame front panel 23. When the lid 3 is in the closed position the inner frame 12 is received in the lid 3 so that the front wall body panel 4 a abuts the inner frame front panel 23. Likewise, the side wall lid panels 6 b, 7 b abut the inner frame side panels 24, 25. Therefore, the inner frame front panel 23 and side panels 24, 25 provide an additional layer of material around the opening 11 of the pack 1 to provide reinforcement for the front, rear and side walls 4, 5, 6, 7.

The side panels 24,25 of the inner frame 12 further comprise side reinforcement panels 26, 27 that each meet a corresponding side panel 24, 25 at a second fold line 18, 19 which extends in a direction parallel to the first fold line 16, 17. The side reinforcement panels 26, 27 are folded at the second fold line 18, 19 so that a major surface of each side reinforcement panel 26, 27 abuts against a major surface of a corresponding side panel 24, 25 to form a double layer. The side reinforcement panels 26, 27 are preferably folded about respective second fold line 18, 19 in the direction down into the page when viewing FIG. 2 so that they lie against an inner surface of the side panels 24, 25, i.e. the surface of each of the side panels 24, 25 which is not visible in FIG. 2. However, the side reinforement panels 24,25 may alternatively be folded about respective second fold line 18, 19 in an opposite direction, so that they lie across a front face of the side panels 24, 25, i.e. the face of each of the side panels 24, 25 which are visible in FIG. 2. The side reinforcement panels 26, 27 may be held against the side panels 24, 25 using an adhesive. The use of adhesive may further increase the robustness and rigidity of the inner frame.

The extra layer of material provided by the side reinforcement panels 26, 27 against the side panels 24, 25 improves the rigidity and durability of the inner frame 12 and forms a dual layered side wall. Therefore, the contents of the pack 1 is better protected against external forces applied to the pack 1. In one embodiment, each side reinforcement panel 26, 27 may overlap the whole surface area of a corresponding side panel 24, 25, i.e. each side reinforcement panel 26, 27 may be the same size and shape as a corresponding side panel 24,25. However in an alternative embodiment each side reinforcement panel 26, 27 may be of a different size or shape to its corresponding side panel 24,25 and so may only overlap a portion of a major surface of corresponding side panels 24, 25.

The inner frame 12 may include tabs 20 that extend from the side walls 14, 15 to engage the side wall lid panels 6 b, 7 b when the lid 3 is in the closed position to increase the friction between the lid 3 and the inner frame 12, although these are optional. The increased friction provided by the tabs 20 increases the resistance to the opening of the lid 3, enabling the lid 3 to better stay in the closed position.

It will be appreciated that, in another embodiment one or more further side reinforcement panels may extend from the side reinforcement panels 26, 27 and be separated from the side reinforcement panels 26, 27 by a fold-line. The side panels 24,25, the side reinforcement panels 26, 27 and any additional side reinforcement panels provide a multi-layered structure to the inner frame , i.e a side wall having more than two layers.

A blank 31 for an inner frame 12 of a second embodiment of the invention is shown in FIG. 3 and is identical to the first embodiment, with like features retaining the same reference numerals, except that each second fold line 18, 19 extends in a direction perpendicular to the first fold lines 16, 17. In this embodiment, the side reinforcement panels 26, 27 are folded in the direction down into the page when viewing FIG. 3, although they could also be folded in the opposite direction.

As mentioned above in connection with the first embodiment, additional side reinforcement panels may extend from the side reinforcement panels 26,27 to enable a multi-layered structure to be formed. Furthermore, a combination of the embodiments shown in FIGS. 2 and 3 is envisaged in which there is a side reinforcement panel 26, 27 extending from both edges of each side panel 24, 25.

Although in the above described embodiments the second fold lines 18, 19 are described as extending in a direction perpendicular or parallel to the first fold lines 16, 17, the second fold lines 18, 19 may alternatively extend at some other angle to the first fold lines 16, 17.

A blank 41 for an inner fame 12 of a third embodiment of the invention is shown in FIG. 4. The blank 41 comprises a front panel 23 that meets side panels 24, 25 at first fold lines 42, 43. The blank 41 is folded at each first fold line 42, 43 so that the side panels 24, 25 extend at right angles to the front panel 23. A front reinforcement panel 28 meets the front panel 23 at a second fold line 44. The front reinforcement panel 28 is folded at the second fold line 44 so that a major surface of the front panel 23 overlaps the front reinforcement panel 28. The blank 41 further comprises side reinforcement panels 26, 27 that each meet the front reinforcement panel 28 at a third fold line 45, 46. The side reinforcement panels 26, 27 are folded at the third fold lines 45, 46 so that each of the side reinforcement panels 26, 27 overlaps a corresponding side panel 24, 25. The side reinforcement panels 26, 27 and/or front reinforcement panel 28 may be held against the corresponding inner frame side panels 24, 25 and/or front panel 23 by adhesive which may further increase the rigidity and robustness of the inner frame.

The increased thickness provided by the front reinforcement panel 28 further improves the rigidity and durability of the inner frame 12 and provides a multi-layered front wall. Additionally, the increased rigidity and thickness of the inner frame 12 provided by the front reinforcement panel 28 increases the friction between the inner frame front panel 23 and the front wall lid panel 4 b, thus helping the lid 3 to stay in the closed position.

It will be appreciated that either of the first or second embodiments may also be modified so as to provide the inner frame 12 of these embodiments with a front reinforcement panel 28 that extends from the front panel 23 and which is foldable so that it overlaps the front panel 23 by folding it about a fold line 44, similar to that shown in FIG. 4. In these embodiments, the front reinforcement panel 28 will not have the side reinforcement panels 26, 27 extending from them, as these extend from the front panel 23 in the embodiment of FIGS. 2 and 3.

Although in the above described embodiments the front reinforcement panel 28 and side reinforcement panels 26, 27 are held in place by adhesive which may further increase the robustness and rigidity of the inner frame. However, in alternate embodiments (not shown) they may be held in place by other means or, they may just be held in place as a result of the pressure applied to the inner frame by the walls of the pack and the tobacco industry products contained therein.

It shall be appreciated that the present invention is not limited to both the side walls and the front wall of the inner frame comprising a double or multi-layered structure. In any of the embodiments described above only one of the side walls may be formed with a double or multi-layered structure. Alternatively, only one of the side walls and the front wall are formed with multiple layers, or only the front wall is formed by multiple layers.

Although in the above described embodiments the side reinforcement panels 26, 27 and front reinforcement panel 28 are integrally formed with the side panels 24, 25 and front panel 23 respectively and are positioned by means of folding, in an alternate embodiment (not shown) the side reinforcement panels 26, 27 and/or front reinforcement panel 28 may be separate sections of material that are arranged against respective side panels 24, 25 and/or front panel using adhesive.

Although in the above described embodiments the inner frame 12 is described for use with a hinged-lid pack, in alternate embodiments (not shown) the inner frame may be used with other pack designs, for example, slide-packs or telescopically extending packs.
